CURTAIN-POLE RING.

Specification of Letters Patent.

Patented May 18, 1909.

Application filed May 1, 1908. Serial No. 30,323.

To all whom it may concern:

Be it known that l, Fnnnnron BARTHOLO- MAE, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Imroved Curtain-Pole Ring, of which the folowing is a full, clear, and exact description.

The invention relates to curtain pole rings such as shown and described in Letters Patent of the United States, No. 87 6,199, granted to John Kroder January 7, 1908.

The object of the present invention is to provide a new and improved curtain pole ring, having anti-friction rollers carried in bearings attached to flattened portions of a tubular ring in a very simple and efficient manner, thus permitting convenient and quick assembling of the parts without re quiring the employment of highly skilled labor.

The invention consists of novel features and arts and combinations of the same, whic will be more fully described hereinafter and then ointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 IS a face view of the curtain ring in position on the curtain pole, the latter ap pearing in cross-section; Fig. 2 is a plan view of the same one of the rollers being removed; Fig. 3 is a transverse section of the same on the line 3-3 of Fig. 1; Fig. 4 is an enlarged longitudinal section of the same on the line 4-4 of Fig. 2; and Fig. 5 is a perspective view of the frame carrying the friction roller.

Th hollow or tubular ring A is reduced on opposite sides of the top of the ring by flat tening corresponding portions A, each flattened portion A being provided with a slot A for the reception of an anti-friction roller B having a shaft or spindle O engaging bearings D formed in a frame D extending transversely on the under side of a flattened por tion A and having its ends D bent u wardly and inwardly onto the ends A of tie flattened ortion A. The frame D is provided wit an opening D registering with the opening A in the flattened portion A of the ring A, so that the anti-friction roller B is free to turn and travel on the curtain pole E, as indicated in Figs. 1 and 2.

The frame D is provided at the bearings D with upwardly extending lugs D engaging the ends of the shaft or spindle C, so as to hold the same against movement in the direction of the axis of the shaft or spindle C.

Now by the arrangement described the several parts can be cheaply manufactured and readily assembled, it being only neces sary to place the anti-friction roller B with its shaft or spindle C in position in the frame D, and then to engage the frame D with the under side of the flattened portion A and to bend the ends D upwardly and inwardly over the ends A of the flattened portion A.

A curtain pole ring constructed as shown and described can be cheaply manufactured, and the various parts readily assembled to rend er the ring exceedingly strong and durable.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent:

1. A curtain pole ring, comprising a ring having a flattened portion provided with a slot, an anti-friction roller extending into the said slot, and a frame attached to the flattened portion and in which the said antifriction roller is journaled.

2. A curtain pole ring, comprising a ring having a flattened portion provided with a slot, an anti-friction roller extending into the said slot, a frame having bearings for the shaft of the said anti-friction roller to turn in, and means carried by the frame for attaching it to the said flattened portion.

3. A curtain pole ring, comprising a ring having a flattened portion provided with a slot, an anti-friction roller extending into the said slot, and a frame having bearings for the shaft of the said anti-friction roller to turn in, the ends of the said frame being bent onto the ends of the said flattened por tion.

4. A OLlIiDEtill pole ring provided with a roller frame having an opening for the passage of the roller, and bearings at the sides for the roller shaft, the frame having in tegral means at its ends for attachment to the pole ring.

5. A curtain pole ring, comprising a ring having a slot therein, a frame extending transversely of the ring, said frame being name to this specification in the presence of pyllovilded twilth an opejlning registering kv)vith two subscribing Witnesses. t e s 0t 0" t e ring am having its ends ent 7 upon the ring, and a roller mounted in the FREDRIOH BARTHOLOMAE 5 o ening of the frame and extending into the Witnesses:

s 0t of the ring. GEORGE KRODER, In testimony whereof I have signed my JAS. P. CLARK.
